Abstract
A wideband buffer circuit and a wideband communication circuit that uses the wideband buffer circuit. The wideband buffer circuit includes first and second transistors deployed as a voltage buffer and connected to first and second input terminals, first and second parallel resistor-capacitor pairs connected to the first and second transistors, first and second cross-coupled transistors connected to the first and second parallel resistor-capacitor pairs and connected to first and second output terminals, and first and second current sources connected to the first and second cross-coupled transistors and a fixed voltage. The first transistor, the first parallel resistor-capacitor pair, the first cross-coupled transistor and the first current source are connected in series. The second transistor, the second parallel resistor-capacitor pair, the second cross-coupled transistor and the second current source are connected in series.
